“Unable to Open Project”

Hello, 

I was working on a project,it crashed many times today but I kept opening it and editing until just now it shows "unable to open project. It is my assignment project, I really wish that you could help me with retrieving my project as soon as possible.

I have the latest version of Rush, IOS 13.2 on my iPad Air 2019.

Questions:

1. Did you enable and disable project sync before the issue occurred? Yes
2. How long were you editing the project before the problem occurred? Two days (6 hours)
3. Did you successfully close and re-opened the affected project previously? Yes
4. Do you remember what effects and features were used, beyond audio and video (e.g. titles, filters, etc). I used a lot of "range speed". That's it. 
5. Did Rush crash before this issue occurred? Yes. It worked very well when I did my last project, no issues at all. Yesterday I started the new current project, it was fine (length edited =5 mins). As today I continued to work on it, it kept crashing and now I can't even open the project.

Please let me know what I should do to open and edit my project again.
